FRIEDRICH WILHELM OEBURG, OF NEW YORK, N. Y.

WAGON-BRAKE.

SPBC IPICATION forming part of Letters Patent No. 423,695, datedMarchlQ, 1890.

Application filed January 18, 1890. Serial No. 337,377. (No model.)

To all whom it may concern:

Be it known that I, FRIEDRICH WILHELM OEBURG, of New York city, NewYork, have invented an Improved Wagon-Brake, of which the following is aspecification. r

This invention relates to a wagon-brake that will automatically lock thehind wheels as soon as the horses are pulled back.

It consists in the various features of improvement more fully pointedout in the claims.

In the accompanying drawings, Figure 1 is a vertical longitudinalsection of a wagon provided with myimproved brake on line at 00, Fig. 2.Fig. 2 is a bottom view thereof; Fig. 3, a vertical longitudinal sectionon line y y, Fig. 2 5 Fig. 4, a vertical transverse section on line 2 a,Fig. 2; Fig. 5, a rear view of the rear axle, showing one of theclutches in section. Fig. 6 is an end viewiof one of the clutches withthe wheel removed, and Fig. 7 is a top view of ring a.

The letter a represents a sliding bar placed below the reach a of awagon, and guided by a clip a At its forward end the bar a terminates ina circular plate a having a long and narrow central slit or eye. Throughthe plate a passes the king-bolt b, and thus it will be seen that,though the bar is secured in place, it is free to slide backward andforward. Around the rim of circular plate a there is placed an annularplate 0, which is free to revolve around plate a. .To the plate a thehorses are hitched by an arm 0', carrying the coupling 0 for the tongueor thill. To the annular plate a may also be secured the lower segmentof the fifth-wheel 0 The pull of the horses, whether directly in frontof the vehicle or turned to the side, will, by the annular plate 0, betransmitted to rod to to draw the same forward. The rear end of rod a isconnected to the clutch mechanism that engages the hind wheels, andwhich is of the following description: Beneath the rear axle cl areguided, by means of clips cl, the brake 'ods (1 carrying clutches orbrakes d, that engage corresponding surfaces on the hubs d. At the innerends the brake-rods are separated by a strong spring d coiled around apin d, that enters the ends of the rods 01 to stifien -the structure.The rods (1 are connected to d will be drawn toward each other by levers7 (1 against the action of spring d to take off the clutch or brake. Assoon, however, as the horses are pulled back, the annular plate 0 willno longer draw bar a forward, and the spring d will force the rear endsof rods 01 asunder, thus at the same time pulling bar a backward andputting on the brakes.

In order to permit the brakes to be put 011 or taken off at will by thedriver, I have devised the followingconstruction: Into the slit of thecircular plate a enter two conical noses e e, one engaging the forwardend of the slit and the other the backward end thereof. In order toguide the noses into the slit, the upper face of the plate a is providedwith the tapering projections a Fig. 3. The noses 6 e are connected tothe rods ff, respectively, reaching into the Wagon-body, where they areprovided with the treadles g 9'. Each rod is retained in its raisedposition by a coiled spring h h. It the driver presses upon treadle g,he will cause the nose 6 to engage the forward end of the plate a and hewill thus draw the rod a forward and take 01f the brakes. If the driverpresses upon treadle g, he will cause the nose 6 to engage the rear endof the plate a and will thus push or retain the rod a in its backwardposition, to put on or close the brakes. A pair of catches i z, pivotedto the bolster j or to any other part of the wagon, serve to hold thenosese e in engagement with the plate a when such noses are depressed.In this way the brakes can be either applied or taken off foranylengthof time.

What I claim is p 1. The combination of a wagon with a sliding barhaving circular plate a an annular plate 0, surrounding plate a andcarrying the shaft coupling, and with a brake-controlling mechanismconnected to the sliding bar, substantially as specified.

2. The combination ofa wagon with a sliding bar having slitted plate aan annular plate 0, surrounding plate a and'carrying the shaft-coupling,a nose engaging the slitted foot-rod, a catch for locking the nose, and.a

plate, and abra'ke-controlling mechanism con' brake-controlling,mechanism connectecl' t0 the 10 nected to the sliding bar, substantiallyas sliding bar, substantially as specified. s eeified. 1 5 3: Thecombination'of a wagon with a slid- FRIEDRICH 'L OEBURG' ing bar havingslitted plate a a surrounding Witnesses: annular plate 0, carrying theshaft-coupling, F.
